7. Parallel Processing Architectures for AI
Parallel processing architectures play a critical role in enhancing the computational capabilities required for AI applications, especially in deep learning. By executing multiple tasks simultaneously, these architectures facilitate efficient data processing and real-time inference while addressing efficiency challenges such as synchronization overhead and memory bandwidth limitations. The chapter emphasizes the importance of hardware selection, memory architecture, and scalability in designing effective parallel processing systems for AI.

What we have learnt
- Parallel processing is vital for handling large datasets and training complex AI models.
- Two primary architectures, SIMD and MIMD, cater to different computational needs in AI applications.
- The design of parallel processing systems must consider factors like hardware selection, memory throughput, load balancing, and scalability.
Key Concepts
- -- Parallel Processing
- Simultaneous execution of multiple computations to enhance performance and efficiency, particularly in handling large datasets in AI.
- -- SIMD
- Single Instruction, Multiple Data - a parallel architecture that applies the same instruction to multiple data points simultaneously.
- -- MIMD
- Multiple Instruction, Multiple Data - a flexible architecture where different processors execute different instructions on different datasets.
- -- Data Parallelism
- Distributing data across multiple processing units to perform the same task on separate data subsets simultaneously.
- -- Task Parallelism
- Distributing different tasks across multiple processors, allowing for concurrent execution of diverse functional units.
